How Many Solar Panels Can I Fit On My Roof?

2 min read

It’s important to make sure your roof has enough space to accommodate enough solar panels to meet your home’s electricity needs. Fortunately, electricity use tends to correspond to house size. As you might expect, the more rooms your home has, the more electricity the home is likely to use. Since the amount of solar panels you’ll need will likely correspond to the size of your home, your roof shouldn’t have any problem fitting that amount. For a more specific discussion on how many solar panels you may need, keep reading the article below. 

But First… How Many Solar Panels Would Fit On Your Roof?

If you are really curious about how many panels could be placed on your roof, let’s do the math. Our solar panels are roughly 70×40 inches, or about 19.4 square feet. Assuming your entire roof is suitable for solar panel placement with ideal sunlight conditions, direction and angles, and that you have a roof size of 2,000 square feet, you would be able to fit 103 solar panels on your roof. That’s a lot of solar power! It’s so much power, in fact, that it’s much more than the average home would be able to use. 

The Real Question: How Many Solar Panels Do You Need?

Ultimately, the question does not come down to how many solar panels you can actually fit on your roof, but the optimal number of solar panels for your home’s specific needs. As mentioned above, that number may be less than you think! 

With efficiency ratings of approximately 20 percent for top-of-the-line solar panels like the tier-1 monocrystalline solar panels Pink Energy offers, your solar panels will receive plenty of sunlight during peak daylight hours to power your home. Twenty percent may not seem like a large number, but in terms of energy, it’s more than enough! Your solar panels will get exposed to approximately 5 peak hours of sunlight each day. Given that the solar panels that Pink Energy installs are approximately 350 watts each, you’d receive about 1.75 kWh each day from each solar panel. The average home uses about 30 kWh per day. So from that, we can determine that about 17 solar panels would potentially generate enough electricity to power the average home. 

Twenty panels would take up approximately 23 percent of the roof space of the average U.S. home, which gives you plenty of room for positioning them for optimal direct sunlight exposure. Depending on your home’s location and the local climate, the number of panels needed will vary. You might even see the average number of panels necessary to power your home decrease over time too — with solar technological advancements on the rise, solar panels become more efficient and able to produce more in less space.
